MagnesiumFreeze is a cream, and its maker, Peak Health Research, lists these ingredients: magnesium chloride, niacinamide (vitamin B3), vitamin B6, arnica, boswellia, menthol, camphor, peppermint oil, tea tree oil, vitamin E, shea butter and aloe vera, in a cooling-then-warming base. The product page prints no amount for any of them, so you can’t compare the cream with the doses used in studies. Human research exists for several of these ingredients on their own, mostly by mouth or for joint and muscle soreness, and the seller points to no trial of the finished cream on nerve pain.

What is in MagnesiumFreeze, ingredient by ingredient?
The seller’s product page says each ingredient has a job in "joint, nerve, and muscle relief." The table puts the seller’s description next to what human research says about that ingredient on its own. Research on a single ingredient, at the dose a study used, is not the same as proof that this cream does the same thing.
| Ingredient | What the seller says it does | What human research says |
|---|---|---|
| Magnesium chloride | Absorbs through skin to support cellular energy and repair; the seller says it beats the magnesium sulfate (Epsom salt) in other creams | Magnesium is an essential mineral involved in nerve and muscle function, according to Cleveland Clinic’s magnesium overview. The studies it describes are of magnesium taken by mouth. Studies of magnesium absorbed through skin have varied widely depending on the magnesium compound, the concentration and the body area. |
| Niacinamide (vitamin B3) | Supports a healthy inflammatory response and tissue recovery | Your body can turn niacinamide into NAD+, a molecule cells use for energy and repair, and that science is real. Most NAD+ research uses oral precursors. No clinical trial has shown that skin-applied niacinamide reaches deep nerve tissue at useful levels. |
| Vitamin B6 | Listed in the product page FAQ, but missing from its "What’s Inside" list, and no role is given | Nerves need B6. The Foundation for Peripheral Neuropathy says both too little and too much B6 can cause peripheral neuropathy. That warning concerns B6 taken as a supplement. |
| Arnica Montana | Traditional botanical for soreness, bruising and swelling | A 2021 review in the journal Medicines looked at arnica trials for post-operative pain, arthritis and musculoskeletal discomfort and found promising effects. Results across studies were mixed. In one randomized trial, arnica gel was not inferior to ibuprofen gel for hand osteoarthritis over 21 days. These were not nerve-pain studies. |
| Boswellia (frankincense) | Studied for joint comfort | Most clinical studies used oral boswellia for joint health, not a cream aimed at nerves. |
| Menthol and camphor | Immediate cooling that calms surface pain signals | These create a sensation on the skin. The seller itself says menthol-only creams cool for about 20 minutes and then fade, and argues this cream goes further. |
| Peppermint oil and tea tree oil | Natural cooling and soothing agents | These are botanical oils. If you react to essential oils or botanicals, ask a pharmacist before using the cream. |
| Coolact and Hotact | A trademarked cooling-then-warming system; the seller says the warming phase increases circulation | These are the seller’s brand names for the cooling and warming agents. The product page does not say what compounds they are or how much is in the jar. |
| Vitamin E | Antioxidant support for skin health | The Foundation for Peripheral Neuropathy notes studies of oral vitamin E (300-600 mg a day) for chemotherapy-related neuropathy. A skin cream’s amount is not listed. |
| Shea butter and aloe vera | Moisturizing base that is gentle on sensitive skin | This is the carrier, not an active ingredient for nerve pain. |
Why are the amounts a problem?
The seller’s homepage says its ingredients are "dosed at amounts that studies support," and a quote from Dr. Karen Vieira, PhD, says the ingredient selection and dosages across Peak Health’s formulas "reflect published research." Yet the MagnesiumFreeze page prints no amount for any ingredient. It also cites "a 13,000+ person study on magnesium and discomfort" without naming it.
That matters because a study result only transfers if the dose and delivery route match. Before you order, email support@peakhealthresearch.com or call (888) 811-1186 and ask for three things: the full label with amounts per application, the complete list of inactive ingredients, and the citation for that 13,000-person study. Then check the study using our guide to reading a study. If it is a registered trial, this trial-record guide shows what to look for.
Does MagnesiumFreeze work for neuropathy or foot nerve pain?
The seller markets it for "burning feet, tingling hands, and shooting leg discomfort," and says relief starts within 15 minutes, with deeper effects building over 1-2 weeks of daily use. Those claims rest on the seller’s own testimonials and its 4.8/5 rating. The page itself carries the standard notice that its statements have not been evaluated by the FDA and that the product is not intended to diagnose, treat, cure or prevent any disease. The seller’s terms also say it does not guarantee you will reach your health goals.
Foot nerve pain is a symptom with many causes, and the cause decides what helps. The NHS says treatment for peripheral neuropathy starts with treating the underlying cause. Nerve pain usually does not respond to common painkillers like paracetamol and ibuprofen. The main medicines are amitriptyline, duloxetine, pregabalin and gabapentin, and capsaicin cream or patches can be used for pain in a specific area. A magnesium-and-botanicals cream is not on that list. A cooling sensation may feel good, but that is different from treating the nerve problem.
One safety point for numb feet: Cleveland Clinic’s peripheral neuropathy guide lists burns as a complication when you cannot feel pain. If you have numb patches, ask a clinician before using anything that warms the skin.
Does it work for sciatica?
The seller does not claim to treat sciatica in its disclaimer, but one testimonial describes shooting pain down the leg and the page points to the lower back and hips as places to apply it. Sciatica-type pain usually comes from a nerve irritated or pinched near the spine. Cleveland Clinic lists herniated disks and other compression as causes of nerve problems, and a Texas pain clinic’s neuropathy guide notes that spinal nerve compression can feel like neuropathy. A cream acts on skin, so it cannot tell you what is pressing on the nerve. If leg pain is new, severe or spreading, an exam comes before any product.
Quick answers to the nerve-pain questions people ask
What is the number one vitamin for nerve pain?
There isn’t a single one. Vitamins matter when you are low in them. Cleveland Clinic lists deficiencies in copper and vitamins B1, B6, B9, B12 and E as causes of neuropathy, and the NHS says B12 deficiency can be treated with injections or tablets. A blood test shows whether that applies to you. The Foundation for Peripheral Neuropathy warns not to start supplements without a doctor, because some have side effects, and B6 can harm nerves at high intake.
What vitamin will repair nerve damage?
None is promised to repair it. Fixing a real deficiency can stop damage from getting worse, and in some cases improve it. The NHS says the evidence for supplements such as benfotiamine (a form of B1) and alpha-lipoic acid is not always clear.
Can nerve damage in the foot heal itself, or be reversed?
Sometimes. Cleveland Clinic says certain neuropathies can be stopped or reversed if diagnosed and treated quickly, and that the more severe and longer-lasting the damage, the less likely it is to reverse. The NHS says that controlling diabetes may improve neuropathy or at least stop it getting worse. Long-standing diabetic or chemotherapy-related neuropathy may not fully go away, but treatment can often reduce pain and protect the feet.
What triggers foot nerve pain?
Diabetes is the most common cause overall and often hits the feet first. Other causes include vitamin deficiencies, heavy alcohol use, certain medicines including chemotherapy, infections such as shingles, kidney or liver disease, autoimmune conditions, injuries, toxins, and pinched nerves. Sometimes no cause is found.
What works immediately for nerve pain?
Nothing reliable. The NHS says nerve-pain medicines are usually started at a low dose and raised gradually. Side effects such as tiredness and dizziness often ease after a week or two. A cooling cream may take the edge off for a short time, but a prescriber is the person to ask about faster options.
What is the worst thing you can do, and is there a drink that stops it?
The sources describe no drink that stops sciatic or nerve pain. Excess alcohol is a known cause of neuropathy, according to Cleveland Clinic. The costly mistake is ignoring warning signs. Cleveland Clinic and the Texas clinic both say to get care promptly for rapidly worsening weakness, balance problems or falls, open sores on the feet, signs of infection, or new numbness. Sudden numbness with facial drooping, confusion or trouble speaking is an emergency.
What will permanently make sciatica go away?
That depends on what is irritating the nerve, which a clinician has to find. No cream, vitamin or drink in the sources is shown to fix it permanently.
What are the side effects of MagnesiumFreeze?
The product page lists no side effects or warnings. It describes the base as gentle on sensitive skin, says the cream does not interfere with oral medications, and recommends checking with your doctor or pharmacist first. Because it contains menthol, camphor and botanical oils, the practical thing to watch is how your skin reacts where you apply it. Ask a pharmacist if you have sensitive skin, botanical allergies, take medications, are pregnant or nursing, or have a medical condition.
Cleveland Clinic’s list of too-much-magnesium symptoms (muscle weakness, nausea, vomiting, low blood pressure, fatigue) comes from magnesium supplements taken by mouth. The seller says the cream bypasses digestion, and it gives no information on how much magnesium enters your body from it. If you have a reaction, tell the seller and your clinician, and consider reporting it using our product-concern reporting guide.
How often should you use it?
The seller’s directions are to apply a quarter-sized amount to the sore area, rub it in circular motions for 30-60 seconds until absorbed, and repeat 2-3 times a day (morning, midday and before bed). It names knees, lower back, feet, hands, neck, shoulders and hips as places to use it. The seller says one jar lasts 30 days when used on 1-2 areas, so using it on more areas will empty it sooner. Ask your clinician before using it on broken skin or numb areas.
What does it cost, and how do refunds work?
Prices as of September 8, 2026; check the checkout for today’s.
| Package | Price per jar | Shipping |
|---|---|---|
| 1 jar | $49.99 | $9.99 |
| 3 jars | $39.99 | Free |
| 6 jars | $29.99 | Free |
The seller’s own pages disagree in places. The product page’s add-to-cart button showed $239.94 beside the 6-jar price, though six jars at $29.99 would come to $179.94. The seller’s shop listing shows $59.99, and its shipping policy page says $6.95 for a one-bottle order. Trust the total at checkout, and screenshot it.
The seller promises a 180-day money-back guarantee. Its returns page says you must email support@peakhealthresearch.com or call (888) 811-1186 with your order number and reason. The item must be in the condition you received it, in its original packaging, with proof of purchase, and some situations get only partial refunds. The seller’s support page says refunds take 5-10 business days to appear. Its product page says "no hoops," so ask support up front whether you must ship the jar back and who pays the return shipping.
The seller also has MagnesiumFreeze cancellation pages, and its support FAQ addresses people charged for orders they did not expect. Look at the checkout for a subscription or auto-ship option before you pay, and keep your order confirmation. The cancel page plays a video and offers a discount before the cancel button.
Where do you buy it, and what about Amazon, Walmart and reviews?
The seller sells it at its official site, peakhealthresearch.com. Its terms say reselling outside its authorized channels can change the product, which may affect safety, effectiveness or its ability to honor guarantees. If you spot a listing on Amazon or Walmart, ask the seller whether the 180-day guarantee covers it before you buy.
The 4.8/5 rating, the "200,000+ jars sold" line and the named testimonials all appear on the seller’s own page, so they are marketing, and you cannot check them independently. The seller does not link its testimonials to a source you can verify, and the same "200,000+" figure appears on its other product pages. For a fuller list of questions to put to any seller, see our pre-purchase question guide.
Before you order
- Ask support for the full label with amounts per application and the complete inactive-ingredient list.
- Ask whether vitamin B6 is in the cream, since the product page lists it in the FAQ but not in its ingredient list.
- Ask for the citation for the "13,000+ person study."
- Ask whether you must send the jar back for a refund, who pays return shipping, and what triggers a partial refund.
- Check the checkout for subscription or auto-ship terms, and confirm the final total.
- If your pain is new, spreading, or comes with weakness, balance trouble or numbness, get the cause checked first.
